Install Elasticsearch 5.x on Ubuntu 16.04

In this tutorial I'm going to show you, how to install Elasticsearch 5.x on your Ubuntu Xenial (16.04) Linux box.

Before you start! Please take a look at the official documentation!

All commands needs to run as user root or via sudo.


Elasticsearch 5.x requires Java 8 or later. If you don't have Java installed yet - follow this guide.

The Elasticsearch APT repository is using HTTPS. For this reason, you need to install the following package.

apt-get install apt-transport-https

Install Elasticsearch

Add official the APT repository to your sources.list

echo "deb stable main" > /etc/apt/sources.list.d/elastic-5.x.list
wget -qO - | apt-key add -
apt-get update


apt-get install elasticsearch

Configure Elasticsearch

In this case, we are going to setup a standalone Elasticsearch system.

Open the file /etc/elasticsearch/elasticsearch.yml to adjust the following values

#Set the name of your Elasticsearch Cluster statusengine

# Set the name of the current node elastic01

#Path where Elasticsearch should store data /var/lib/elasticsearch

#Path where Elasticsearch should store log files
path.logs: /var/log/elasticsearch

#You need at least one master node inside
#of your Elasticsearch Cluster
node.master: true

#You need at least one node inside
#of your Elasticsearch Cluster, that holds your data true

If one of the listed options is missing in your default config, just add it .

Start Elasticsearch

systemctl enable elasticsearch.service
systemctl start elasticsearch.service

By default Elasticsearch will listen on localhost:9200 and localhost:9300.

You can change this or run an HTTP reverse proxy (for example nginx) in front of Elasticsearch.

root@ubuntu:~# netstat -tulpen | grep java
tcp6       0      0          :::*                    LISTEN      111        32142       9731/java
tcp6       0      0 ::1:9200                :::*                    LISTEN      111        32141       9731/java
tcp6       0      0          :::*                    LISTEN      111        32100       9731/java
tcp6       0      0 ::1:9300                :::*                    LISTEN      111        32091       9731/java
Test Elasticsearch

To check if your installation of Elasticsearch is running, you can run a simple status query against it.

curl -X GET "http://localhost:9200"

You should get an result like this:

  "name" : "elastic01",
  "cluster_name" : "statusengine",
  "cluster_uuid" : "Iz8f3T6pQQ62k_asARql-w",
  "version" : {
    "number" : "5.6.3",
    "build_hash" : "1a2f265",
    "build_date" : "2017-10-06T20:33:39.012Z",
    "build_snapshot" : false,
    "lucene_version" : "6.6.1"
  "tagline" : "You Know, for Search"

Setup Cerebro

Cerebro (previously known as kopf), is an web based admin tool for Elasticsearch. Especially if you are new to Elasticsearch it will help you a lot!

Before you start! Please check for newer version at the official GitHub repository!

cd /tmp
tar xfv cerebro-0.7.1.tgz
cd cerebro-0.7.1/
mkdir -p /usr/local/share/cerebro
cp -r * /usr/local/share/cerebro/

Now you can run Cerebro using this command:


You should now be able to access Cerebro via your Webbrowser: http://<ip-address>:9000

In addition, you can add a systemd service, to run Cerebro as service in the background. Create the file /lib/systemd/system/cerebro.service:



systemctl daemon-reload
systemctl start cerebro.service
